Their are many crypto exchange sites with different annual interest simply for a customer holding his or her coin in an idle mode via their platform. I find it so hard to discover most of the exchange sites rates per annum for keeping my coins idle in their respective wallet.
I've learned about Coinbase, and the percentage per annum they offer for saving the coins in with them, which is around 4-5% annual interest. Whereas Binance exchange offers 8% annual interest for customers to holdl their coins.
I know others might offer higher than what Coinbase and Binance exchange offers at the moment per annum keeping it idle. I never used trust-pilot, a sister site to Binance exchange when it comes to crypto transactions, some users say they also offer higher interest rate. I've heard about Coinomi, blockchain.com, Crypto.com, Huobi global, Coingecko etc, but I don't know how much they offer per annum holding the coins in their respective sites.
On your own, which crypto exchange/wallet site offers the best interest rate per annum holding the coins in an idle mode?
Your response will be highly appreciated, thank you.
